According to Chandrasekhar Limit, the mass of an object can not exceed than 1.4 times the mass of the sun. But according to some other theories, the sun was very large at former times and earth and ...

Two quick questions regarding the origin of our Sun:
Our own Sun was probably part of a much larger gas cloud and I wonder, if two distinct stars condense from a homogenous protocloud, do very slight ...

I was watching this video on the YouTube channel Veritasium. In this episode, the host shows people paper containing holes of different shapes in the middle. So there is a paper which has a hole in ...

When Jupiter formed I assume like the other planets it started as tiny clumps of matter that eventually came together, became gravitationally bound and then eventually captured a lot of gas. I've also ...

Trying to find an answer to this question, I came across two different methods of determining whether electrons at the center of the sun are degenerate or not.
The first method, used here, calculates ...

I know that a gas behaves more like an ideal gas at higher temperature, and that is very well achieved in the Sun's core. But also low pressure is needed for a gas to behave like an ideal gas, and the ...

I am trying to calculate the surface temperature of the sun with a copper strip. I have a temperature sensor to calculate the temperature of the strip and that's it. Assuming the rate at which energy ...

Alright guys, so I attracted you with the title. Now, to preface the question, I am fully aware of the work of Copernicus, as well as the concepts of Heliocentrism and Barycentric Coordinates. I have ...

It is believed that if earth would have no atmosphere then the sunlight would fall on earth like a spot light. According to this fact the sunlight on moon must fall like a spot light. Does it? Then ...

I will make some 5mm blackened steel letters for a building. Now, in the sunlight in summer, how hot can they get?
EDIT:
i want to place some LEDs on the back of the letters. now the question is if ...

I understand that the loop twisting is the ultimate originator of the CMEs but what causes this twisting? The expansion of the loops is caused by a magnetic pressure differential between the top and ...

Sky looks blue because because our eyes are sensitive to blue colour. But when viewed through a camera why don't we see violet of the sky even though we can see violet colour of other pictures taken ...

Do solar panels generate electricity infinitely?
IF YES then how do the electrons in the n-type which go to p-type then how do those electrons restore themselves. I mean in n-type terminal we have the ...

Alright. So me and some other people right now need an answer to this. If you have 1 trillion lions traveling at 81 kilometers (top speed of a lion) towards the Sun in a pretty dense ball. (As dense a ...

Astronomy is far older than nuclear physics. So there was a long time in which fire was a reasonable explanation for the sun burning.
Has any scientist figured out the sun cannot possibly be a normal ...

The spectrum of the Sun as seen at sea level can be seen at https://commons.wikimedia.org/wiki/File:Solar_Spectrum.png so we can see that wavelengths around green to yellow are the ones that are the ...

I think my title sums it up. Given that we think the dark matter is pseudo-spherically distributed and orbits in the Galactic potential with everything else, then I assume that its speed with respect ...

If I may summarize something I told a friend in a pub...
"We don't get heat from the sun at all. Heat requires matter to move through and there's too much vacuum between the sun and us for any heat ...

As time progresses, which scenario will happen first? The moon colliding with Earth, or the Earth colliding with the Sun? I figure the Moon and Earth will happen first, based on proximity, but the sun ...

Say we can collect all the energy from the sun's output and all the particles from the solar wind. If we had an energy to mass converter and turned everything into say, carbon, how many kilograms of ...

The Schwarzschild radius of the sun is approx. 3 km. It would be a black hole if all the mass of it were within the 3km.
However, even with the mass spread out couldn't the sun technically have a or ...

What is the isotope composition of hydrogen atoms in the sun? Are the ratios of protium:deuterium:tritium similar to those we find on earth?
What does the nuclear fusion of hydrogen atoms in the sun ...
